Sow into trays of Yates Seed Raising Mix, barely cover seed with mix, firm down and moisten. Keep trays in shade and move into more sunlight after germination. Transplant when large enough to handle.
Choose a well drained position in full sun but sheltered from the wind. Add compost and Yates Blood & Bone before planting and fertilise regularly with Yates Thrive Soluble Plant Food. Protect from snails and slugs with Yates Blitzem.
Pinch out early buds until the plants have formed good clumps. Remove spent flowers to promote further blooming. Water at base of plant to avoid disease.
